Metlan Instruments, a renowned global supplier of flow measurement devices, is proud to announce the expansion and consolidation of its oil flow meter product line. This move affirms Metlan’s commitment to offering customers a full-spectrum solution — from highly viscous lubricants and heavy fuel oils to clean refined fuels — covering diverse industrial applications across oil, fuel, lubrication, chemical and refinery sectors.
Why Oil Flow Meters Matter
In many industries — from fuel distribution and storage terminals, to petrochemical processing, lubrication systems, and refinery operations — accurate, repeatable oil flow measurement is the foundation of process control, inventory management, billing / custody transfer, and compliance. Oil types range from light, low-viscosity fuels to heavy, viscous oils and lubricants; the flow meter must handle wide viscosity, pressure and temperature variations while still delivering reliable readings.
Recognizing this diversity, Metlan Instruments structures its oil flow meter offerings to cover virtually all viscosity and flow-range demands, ensuring that clients can always find a “right fit” for their oil flow measurement needs.
Metlan’s Oil Flow Meter Product Lines & Their Strengths
Metlan’s “Oil Flow Meters” umbrella includes several key technologies — each optimized for different oil types, flow conditions, and application requirements.
Positive Displacement (PD) Flow Meters
- Bi-Rotor PD Flow Meter (MT-ABR): High-accuracy (standard ±0.5%, optional ±0.1%) volumetric measurement; wide flow range; robust against viscosity changes and suitable for heavy oils, lubricants, and variable-viscosity fluids.
- Other PD / Gear / Oval-Gear Meters: Ideal for high-viscosity oils, industrial lubricants, heavy fuel oil (HFO), crude oil — especially where viscosity changes or batch control is required.
Why PD Meters? PD meters count discrete volume chambers or rotations to measure volume, making them largely viscosity-insensitive, and capable of maintaining accuracy even when fluid properties vary. They also often do not require long straight-pipe runs, easing installation.
Mass Flow Meters (Coriolis)
Metlan’s Coriolis series delivers direct mass flow measurement with high precision, regardless of changes in fluid density, viscosity, temperature or pressure. This makes them ideal for applications requiring fiscal accuracy, custody transfer, blending verification, and mixed oil streams.
Key advantages: no moving parts, multi-parameter output (mass flow, density, temperature), excellent repeatability, and suitability across light to heavy oils.
Turbine Flow Meters
For situations involving high flow rates with low-viscosity oils (e.g., refined fuels, light lubricants) where cost is a concern, Metlan’s turbine flow meters offer a cost-effective volumetric solution. They perform best when fluids are clean and viscosity stable.
Highlight – Bi-Rotor PD Flow Meter (MT-ABR): A Flagship in PD Technology
The MT-ABR Bi-Rotor PD Flow Meter stands out as a core element of Metlan’s oil flow meter offering. Its key features include:
- High volumetric accuracy (±0.5% standard, ±0.1% optional)
- Wide flow range — suitable from small-scale lubrication circuits to large fuel-transfer lines
- Strong viscosity tolerance — ideal for heavy oils, lubricants, HFO, crude and variable-viscosity fluids
- High pressure rating — compatible with demanding industrial environments
- Robust, low-maintenance design — minimal wear due to rotor mechanics, stable over long service life
These strengths make MT-ABR highly suitable for fuel terminals, lubricant distribution, chemical batching, custody transfer, and any scenario where reliable volumetric flow measurement of viscous or variable oils is required.
Matching Flow Meter Type to Application Needs
Metlan emphasizes a selection principle: match the flow meter’s technology with the oil’s viscosity, flow rate, operating conditions, required accuracy, and maintenance tolerance. Key selection factors include:
- Viscosity: Heavy oils / lubricants → PD or Coriolis; Light fuels / refined oils → Turbine or Coriolis
- Flow rate & volume: Low- to medium-flow / batch control → PD; High flow rate → Turbine or large Coriolis
- Accuracy requirement: Fiscal metering, custody transfer → Coriolis or calibrated PD; General flow monitoring → Turbine or standard PD
- Fluid variability: Frequent changes in temperature, viscosity, or density → Coriolis preferred
- Installation constraints: Limited straight-pipe runs → PD or Coriolis (less sensitive to flow profile)
This structured approach ensures users avoid mismatches — e.g., using a turbine for heavy, viscous oil (likely to cause inaccuracy or mechanical wear), or over-spec’ing expensive Coriolis meters for simple, high-volume clean-oil transfers.
Applications Where Metlan Oil Flow Meters Excel
Metlan’s oil flow meter solutions are widely applicable:
- Fuel distribution and custody transfer (refined fuels, diesel, HFO)
- Lubrication oil monitoring and delivery in industrial machinery
- Refinery & petrochemical process flows — crude oil, intermediate oils, blends
- Hydraulic and lubrication systems requiring precise volumetric control
- Chemical blending and batching where viscous or variable oils are involved
- Inventory management and fuel/oil stock reconciliation
By offering both volumetric (PD, turbine) and mass flow (Coriolis) solutions, Metlan allows flexibility for clients managing diverse oil types and process requirements.
